Background

The sewage pump is a pump product which is connected with a motor and simultaneously submerged into liquid to work, and compared with a common horizontal pump or a vertical sewage pump, the sewage pump has compact structure and convenient installation and maintenance, and a large-scale sewage pump is generally provided with an automatic coupling device to be automatically installed and is quite convenient to install and maintain. The continuous operation time is long. The sewage pump has the advantages that the pump and the motor are coaxial, the shaft is short, the rotating parts are light in weight, so that the load (radial direction) borne by the bearings is relatively small, and the service life is much longer than that of a common pump. The problems of cavitation damage, irrigation and water diversion and the like do not exist. Particularly, the latter point brings great convenience to operators. The vibration noise is small, the temperature rise of the motor is low, and the environment is not polluted. With the continuous acceleration of the progress of the national cities and towns, the rural population is continuously transferred to the cities and towns, the urban area and the population are continuously increased, and the amount of wastewater is also continuously increased; meanwhile, people pay attention to the environment, production sewage, domestic sewage and initial rainwater need to be treated in a centralized manner and then discharged, desilting is needed in some sewage storage places, and a sewage pump is needed for lifting and conveying; in the prior art, various scum, plastic products or other similar matters generally exist in sewage, and the impurities block a water inlet, so that sewage is conveyed smoothly, normal work of a sewage pump is affected, damage of a motor is caused, the work efficiency of the sewage pump is reduced, and the service life of the sewage pump is shortened.
